Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings, but is not limited to the content described below.

[0021] Referring to Fig. 1, it is a diagram of the overall structure of the hoop involved in a method for realizing the dynamic balance of the carbon fiber composite shaft tube of the present invention, including the hoop 1, bolts, nuts and spring washers 5. Among them, the clamp 1 is composed of four quarter-circle clamps, and the quarter-circle clamps are composed of bolts, nuts and spring washers 5 (the spring washers are placed between two adjacent quarter-circle clamps). The bolts of a round clamp and then fastened with nuts) are connected to form a complete circular clamp 1.

[0022] On the circumference of the complete circular clamp 1 (the side or axial surface of the clamp 1), some threaded holes 4 are evenly arranged (the axis of the threaded hole is parallel to the axis of the clamp), and the number of threa...

Abstract

The invention discloses a process method for achieving dynamic balance of a carbon fiber composite transmission shaft and a used combined dynamic balance clamping hoop device. The dynamic balance device comprises a clamping hoop, bolts, nuts, spring gaskets, balancing weights and balancing weight set screws. The clamping hoop is composed of four quarter round clamping hoop bodies which are connected through the bolts, the nuts and the spring gaskets. The integrated round clamping hoop is formed on a carbon fiber composite tube in the circumferential direction. Threaded holes used for fixing the balancing weights are uniformly distributed in the circumference of the round clamping hoop. The device is simple in structure, the carbon fiber composite transmission shaft can be dynamically balanced by adopting a weight increment method or a weight decrement method by means of the process method, in addition, operation is convenient when the axial and circumferential positions of the balancing weights are adjusted, drilling weight-decrement is not needed in the carbon fiber composite transmission shaft, the balancing weights do not need to be bonded to the shaft, and dynamic balance of the carbon fiber composite shaft tube can be easily and effectively achieved.

Description

technical field [0001] The invention relates to the field of shaft dynamic balance, in particular to a method for realizing the dynamic balance of a carbon fiber composite material shaft tube, and to a combined dynamic balance clamp device. Background technique [0002] Carbon fiber composite material is one of the most widely used composite materials at present. It has very excellent mechanical properties. Its specific gravity is less than 1 / 4 of that of steel, but its strength is far stronger than steel. Therefore, the use of carbon fiber composite materials is becoming more and more extensive. . The shaft tube made of carbon fiber composite material replaces the traditional metal shaft, which can not only meet the strength requirements, but also reduce the mass of the transmission shaft, which is beneficial to reduce energy loss. [0003] In the manufacturing process of the carbon fiber composite shaft tube, due to problems such as uneven material and manufacturing preci...
